Application filed September 5, 1925.

My invention relates to an improvement in glass molding machines. 7

The present invention is designed more particularly for molding towel-bars and the 5 like in square, round, oblong and other crosssectional forms.

Great ditficulty has been encountered in the past in preventing bending, Warping, and surface cracking. All. this has been ob- 1G viated in my present invention, which consists in a mold adapted to receive the molten glass, a plunger for forcing it out, and a trough of the shape of the article to be formed, out through which the glass is 1.5 forced in the cross-sectional form and size of the trough itself.

The accompanying drawing is a view in perspective.

A, represents the mold; and B, is the 20 plunger Which fits the cylindrical inner Wall of the mold; and 1, is a fragment of the handle of the plunger.

The numeral. 2 represents the spout of the mold; and 3, is the outlet. A trough 4tof 25 the form of the outlet 3 in cross-section is placed adjacent to the outer end of the spent 2, and the charge of glass is forced out through this spout in a quantity approximately to fill the mold, so that the glass is 30 really formed as it issues through the spout, and the form is preserved by feeding and Serial No. 54,785.

during its passage through the trough at. An air nozzle 6, of Which one only of several is illustrated, is adapted to cool the glass as it feeds through the trough. In this way I have found the shape given the bar of glass at the nozzle is preserved perfectly by the shape of the trougl'i, and by the time the completed bar fills, or approximately fills the trough, it is a completed and perfected article. 1

While other forms are not shown, it is obvious that these bars might be made either square as illustrated, oblong, round, or in fact in other crosssectional forms. Thus in a very simple Way provision is made for forn'ling articles of this character simply, cheaply, and with a very high degree and percentage of profit, and With the handling: and processing reduced to a minin'ium.

I claim:

The combination of a glass-rcceivin chamber, an outlet spout of the desired crosssectioual shape and form of the desired artiole, and a trough open on its upper side and of corresponding; cross'section to the outlet adapted to receive the material and preserve
